Dr. Christie M. Sayes is an Associate Professor of Environmental Science and Toxicology at Baylor University. She is a subject matter expert in nanomaterial-related toxicology and exposure. Her activities include working with partners, collaborators, and clients in designing & directing studies and training & advising facility staff. She possesses a working knowledge of laboratory science and U.S. regulatory climates. Routine activities include data collection, analyses, and interpretation as well as results documentation and reporting. Data is always related back to the published literature. Sayes functions as point of contact for study control.

Sayes was formerly a program Director of the environmental health program at RTI International and an Assistant Professor of toxicology at Texas A&M University; she maintains her adjunct faculty appointment at Texas A&M as well as appointments within the University of North Carolina System and Baylor University. She has more than a decade of experience in the fields of nanotechnology and nanotoxicology and has authored numerous publications, including original research, invited reviews, and book chapters. She is a member of the Society of Toxicology and recently served on the Scientific Advisory Board for the EPA’s FIFRA Program. She also serves as Associate Editor for RSC Toxicology Researchand on the Editorial Board of the journals Toxicological Sciences, Nanotoxicology, and Toxicology Letters. Sayes is the Past-President of North Carolina Chapter Society of Toxicology, current Secretary of Lone State Chapter Society of Toxicology. In addition, Sayes serves on the local organizing committee and International Advisory Board for the 8th International Nanotoxicology Conference.

She has proven abilities in providing technical guidance and leadership to students, technicians, and colleagues; a high aptitude for development of complex particle toxicological and biocompatibility basic and applied research projects in cell culture based and animal based models; substantial training in nanomaterial research techniques & instruments; significant experience working independently & collaborating across disciplines and organizations; excellent communication and interpersonal skills with colleagues in science and engineering, senior management, and new and existing clients and other funding sources.

Christie received her PhD in Chemistry in 2005 from Rice University. Her dissertation focused on the nano-bio interface. In 2005, she joined The DuPont Company as Visiting Scientist and aided in the drafting of the DuPont-Environmental Defense Nano Risk Framework.
